Problems
Wind Slabs
Wind slabs are forming in unusual places with variable wind direction. Feel for pockets of stiffer snow before you commit to your line. Treeline hazard is specific to exposed terrain features such as ridgelines.
- Keep an eye out for reverse loading created by North through East winds.
- Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Dry
The problem is specific to steep terrain and will become less of an issue as snow continues to settle with warming temperatures sunday.
- Be careful of loose dry power sluffing in steep terrain.
- Be very cautious with gully features.
Aspects: All aspects.
Elevations: All elevations.
